So I've been doing a number of 20x30 inch prints lately, and would like to go to 30x40 for select images. I've already built a horizontal enlarger for this purpose (My Zone VI is fine for up to 20x30, but not much bigger) - and my plywood/epoxy sink I.D. measures 35"x16Ft.
For the 20x30's, I built trays out of 1/4 inch birch ply then sealed with epoxy - these work great! I could do the same for 30x40's and just barely squeeze them into my sink, but would likely need to rack at least two of these to work with any degree of comfort.
So my latest thought is to construct troughs (with a generous "V" shape to minimize the risk of creasing/folding of the paper) for the four chemical steps (dev/stop/fix1/fix2) - plus a large open tray for holding and wash. I'd then attach clips (stainless or some other non-reactive material) to two 30 inch wooden or plastic dowels (maybe six clips per dowell), and clip then edges of the paper to these so that I can dip-curl-lift-and repeat these without too much risk of creasing or folding.
But recently, while cruising through my local Home Depot - I notice these 30 inch long Wall Paper troughs...a bit expensive (appx 50. each) - but looks like these might just work. My big concern is that these might not be wide enough to allow for a comfortable and safe paper curl radius...again essential to minimize the risk of creasing/folding.
So...anybody tried these troughs? Thanks!
